The aim of this study is to assess the effectiveness of GSK Biologicals' pneumococcal conjugate vaccine (GSK1024850A), administered according to different vaccination schedules, against invasive disease caused by S. pneumoniae or H. influenzae as well as vaccine impact on the occurrence of hospital-diagnosed pneumonia cases, tympanostomy tube placement and outpatient antimicrobial prescriptions.

This study will also explore vaccine impact on occurrence of respiratory tract infections (RTIs), including acute otitis media (AOM) in a subset of children in Turku area.

[ Time Frame: From the administration of the first vaccine dose up to 31 January 2012. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Occurrence of culture-confirmed pneumococcal invasive diseases due to any of the vaccine-related pneumococcal serotypes (in children starting vaccination within the first 7 months of life in clusters assigned to a 2-dose primary vaccination course).

[ Time Frame: From the administration of the first vaccine dose up to study end. ] [ Designated as safety issue: No ]

Occurrence of hospital-diagnosed pneumonia cases with alveolar consolidation/pleural effusion on the CXR (CXR-AC pneumonia) based on the CXR reading according to WHO criteria (in all subjects).

Occurrence of hospital-diagnosed pneumonia cases without alveolar consolidation or pleural effusion on the CXR (CXR-NAC pneumonia) based on the CXR reading according to WHO criteria (in all subjects). [ Time Frame: From the administration of the first vaccine dose up to study end. ] [ Designated as safety issue: No ]

Occurrence of tympanostomy tube placements (in all subjects). [ Time Frame: From the administration of the first vaccine dose up to study end. ] [ Designated as safety issue: No ]

Occurrence of outpatient antibiotic prescriptions (in all subjects). [ Time Frame: From the administration of the first vaccine dose up to study end. ] [ Designated as safety issue: No ]

Antimicrobial susceptibility of S. pneumoniae and H. influenzae isolated from invasive disease (in vaccinated children). [ Time Frame: From the administration of the first vaccine dose up to study end. ] [ Designated as safety issue: No ]

Occurrence of upper and lower respiratory tract infections , including AOM (in a subset of vaccinated subjects in Turku area). [ Time Frame: From the administration of the first vaccine dose up to study end. ] [ Designated as safety issue: No ]
